Randomized controlled trials (RCTs) are one of the most effective methods for producing rigorous evaluations; we are offering a Challenge to encourage the use of RCTs to address criminal justice problems. Contestants will submit completed RCTs to NIJ; the first five contestants who get five successful RCTs will win. A prize of up to $100,000 is available.

On this page, we will be tracking the front-runners in our Randomized Controlled Trial Challenge in Criminal Justice Agencies. The leaderboard will include the submitting agency, the number of RCT's approved and completed, and titles and descriptions of each RCT.
